Also associated methods, kits and uses.

FIELD OF THE INVENTION

The present invention relates to the field of cosmetics, particularlyhair cosmetics, and relates to a composition for providing a film onkeratin fibres.

BACKGROUND OF THE INVENTION

Semi-permanent treatments to human keratin fibres are well known in theart. Of particular note are semi-permanent treatments that alter thecolour appearance of the hair or provide other coloured or reflectiveproperties via the use of glitter or particles. For example, direct dyescolour the hair in a semi-permanent fashion by adhering colouredmolecules to the keratin fibres. The dye can be later washed out. Hairchalks are powder-based or powdery products—typically provided in ablusher-style ‘compact’ or in pen format—that enable the user to applypigments and/or coloured particles to the hair.

A drawback of the known technology in this area is low adherence of thepigment or coloured material to the keratin fibres—it is a seriousconsumer concern that such products can make your clothes and/orbathroom dirty and/or stained. Furthermore, such pigment or colouredmaterial can migrate to the skin on your neck, shoulders and face andcause unsightly marks. Moreover, consumers wish to be able to apply.Chalk products typically provide a matt look, which may not be desiredby all consumers and would not provide a vibrant, shiny look where theconsumer desires this.

Thus there is a need for compositions and methods that provide moredurable means to adhere pigments and/or coloured/shiny material tokeratin fibres. In particular, there is a need for providing improveddeposition of these particles. Furthermore, there is a need forproviding a composition that is able to deposit a wide variety ofparticles—whether pigments, glitter or other coloured material. Inaddition, there is a need for such a composition that can be easilyapplied and distributed over the hair—for example does not result inclumping of the composition, or any kind of gluey-ness or gunky-ness ofany kind on the head of hair. Indeed, there is a need for a more naturallook to be provided by such means.

Teboul WO2014/001391A1, which published on 3^(rd) Jan. 2014 relates to a“process for dyeing keratin fibres, in particular the hair, whichconsists in applying to the keratin fibres: —at least one coat of atleast a first composition (i) comprising at least one hydrophobicfilm-forming polymer, at least one volatile solvent and at least onepigment, and then, after drying the said coat, at least a second coat ofat least a second composition (ii) comprising at least one hydrophobicfilm-forming polymer, at least one volatile solvent and at least onepigment . . . ” Teboul does not disclose an aminosilicone polymercomprising an amino side chain. Maillefer et al in EP2090295A1, whichpublished on 19^(th) Aug. 2009, mentions pigments in §127, but in thecontext of a “method and composition for improving the drying time ofhair”. For example, there is no teaching in Maillefer et al ondeposition enhancers. Calaco et al in WO2013/085577A2, which publishedon 13^(th) Jun. 2013, mentions compositions and methods are disclosedfor imparting a long-wearing color to keratin fibers. However, Calaco etal also does not teach deposition enhancement.

None of the prior art teach or provide solutions that fulfil all theconsumers' needs.

Theory Behind and Advantages of the Present Invention

The inventors provide herein a composition for providing a film onkeratin fibres, more particularly a composition for providing a colouredfilm on keratin fibres. Indeed, the combination of film-formingaminosilicone polymer, silicone resin, thickening system, water andpigment or coloured material results in a film on keratin fibres,particularly human head hair, that is sufficiently durable that it doesnot quickly rub off whilst on the keratin fibres, for example on thehands, clothes etc of the consumer, nor does it provide bad hair feel,such as lumpiness, nor abrasiveness, nor weigh down the hair reducingthe head of hair volume, nor unsightly globules.

Indeed, the film-forming aminosilicone polymer and silicone resin enablethe forming of a very thin, dry film, which tightly binds the colouredmaterial or pigment onto the hair fibres in a durable fashion. Theaminosilicone polymer and silicone resin provides an excellent film viaa crosslinking and dehydration mechanism.

The thickening system can help to prevent dripping of the composition byinhibiting capillary action, which would otherwise quickly draw thecomposition down the fibres and onto the floor and/or clothes of theuser. Nevertheless, the thickening system, particularly the combinationof thickening polymer and deposition enhancer, provide a non-drippingcomposition that adheres well to keratin fibres without generating asticky feel. Moreover, the thickening system does not detract from theability of the film-forming aminosilicone polymer and silicone resin toprovide the thin, dry film.

In particular, the present invention overcomes the drawbacksdemonstrated by previous developments in this area in that it is able toprovide subtle hair effects that can be employed by a much wider varietyof end-consumers in a wider variety of life contexts. In other words,the effects provided by the present invention are not limited to highlyvibrant and dazzling hair effects that are often used prior to visitinga disco or nightclub, but also provides chic hair looks that areacceptable in a business context and also not too overpowering foreveryday hair looks.

Indeed, the selected combination of features—the combination offilm-forming aminosilicone polymer, silicone resin, thickening system,water and coloured material and/or pigments—provide an excellent supportsystem for coloured material and/or pigments, which can provide thedesired effects to the hair, such as glitteriness, colour, shininessetc. Said coloured material and/or pigments may be provided separatelyfrom the composition chassis such that the consumer and/or stylist canselect the exact type of pigment and/or coloured material desired.

Composition of the First Aspect

The composition according to the first aspect is for providing a film onkeratin fibres. The composition may be for providing a film comprisingpigment or coloured material on keratin fibres. The film may be adurable film.

The composition is substantially free of compounds causing precipitationof any component of the composition when the composition is in aqueoussolution at pH 5 and at 23° C.

When the composition typically comprises a film-forming aminosiliconepolymer, a MQ resin, a thickening system, and a solvent, the pH of thecomposition may be between 4 and 6, preferably between 4.5 and 5.5.Examples of compounds causing precipitation of any component of thecomposition when the composition is in aqueous solution at pH 5 and at23° C. may be a basic solvent, or ionic compounds or compounds that arecationic from pH 4 to 6, preferably from pH 5 to 6 or compounds having arelative ionic strength.

Indeed, precipitation of any component of the present composition wouldhave negative side effects on the efficacy of the presentinvention—particularly in terms of hair feel. Indeed, with the exceptionof the pigment and/or coloured material that is herein intended to beimmobilised on hair, other residues on hair are not accepted by theconsumer. For example, precipitation of the film-forming aminosiliconepolymer and/or silicone resin would detract from their ability to form afilm on the hair fibres and would form residues on hair. The compositionmay be substantially free of any further ionic compounds. Thecomposition may be substantially free of any compounds that are cationicat pH 4.0 to 5.0.

Aminosilicone & Silicone Resin

The composition comprises a film-forming aminosilicone polymer, whereinthe aminosilicone polymer comprises amino side chains, and wherein theaminosilicone polymer has a weight average molecular weight of from10,000 Dalton to 60,000 Dalton. “Sidechain” (or “side chain”) in thecontext of a silicone refers to a group being not part of the siliconebackbone nor only present on at least one terminus of the siliconebackbone. “Terminal aminosilicone” as defined herein means siliconecomprising one or more amino groups at one or both ends of the siliconebackbone. Aminosilicone polymers having amino side chains are sometimesreferred to as silicone compounds comprising pendant amino groups. Theaminosilicone polymer may be not a terminal aminosilicone. Thecomposition may be substantially free of silicones having terminal aminogroups.

The aminosilicone polymer is a film-forming aminosilicone polymer. Theaminosilicone polymer may be a polydimethylsiloxane having graft aminogroups.

The aminosilicone polymer may have a weight average molecular weight offrom 15,000 Dalton to 50,000 Dalton, or from 20,000 Dalton to 40,000Dalton.

The aminosilicone polymer may be a polydimethylsiloxane polymer havingpendent (graft) amino groups. The aminosilicone polymer may conform tothe formula:

in which x′ and y′ are integers such that the weight average molecularweight is between 10,000 Dalton and 60,000 Dalton. The endcaps may bemethoxy rather than hydroxyl as pictured in the above formula.

The aminosilicone polymer may be a polydimethylsiloxane polymer having asidechain with from 3 to 8 carbon atoms.

in which n and m are integers such that the weight average molecularweight is between 10,000 Dalton and 60,000 Dalton, R₁ and R₃ areindependently selected from —OH or —OCH₃; R₂ is H or a C₁ to C₃ alkyl,or methyl or H, preferably methyl. “n” may be on average from 1 to 50,or from 5 to 20, or from 6 to 10, or from 8 to 9, and “m” may be onaverage from 120 to 300, or from 150 to 200. “n” may be on average from5 to 8, “m” may be on average from 150 to 180, R₁ and R₃ may be bothmethyl, and R₃ may be —OCH₃.

The aminosilicone polymer may have an amine number of from 0.1 meq/g to3 meq/g, or from 0.7 meq/g to 2.5 meq/g, or from 0.6 meq/g to 1 meq/g.

Suitable example aminosilicone polymers can be found in the followingpatent documents, which are incorporated herein by reference: DecosterU.S. Pat. No. 6,451,747B1 col. 17, 11.4-27; Hughes U.S. Pat. No.5,567,428 col. 13, 11.40-56; Gawtrey et al US2004/0010863A1, §0016 to§0039; Mahr et al US2006/0041026A1.

The composition may comprise from 1% to 15%, or from 1.5% to 5% of theaminosilicone polymer. The viscosity of the aminosilicone polymer may befrom 10 to 100,000 mPa·s, or from 100 to 10,000 mPa·s.

The composition comprises a silicone resin. Silicone resins are known inthe art. The silicone resin may be a film-forming polymer. The siliconeresin is an MQ resin. “M” stands for Me₃SiO and “Q” stands for SiO₄. TheMQ resin may have an M:Q molar ratio of from 0.5:1.0 to 1.5:1.0. Theweight average molecular weight of the resin may be from 1000 Daltons to10,000 Daltons. The MQ resin may contain at least 80 mol. %, or at least95 mol. %, of units of the general formulae below:

R⁷ ₃SiO_(1/2)

SiO_(4/2)

in which R⁷ is C₁₋₄₀ alkyl, H, —OR or —OH radicals. The ratio of theunits of the general formulae may be from 0.5 to 2.0, or from 0.5 to1.5. The not more than 3% by weight, or not more than 2.5% by weight, ofthe radicals R⁷ may be —OR and —OH.

The remaining units of the MQ silicone resin may be units of thefollowing general formulae:

R⁷ ₂SiO_(2/2)

R⁷SiO_(3/2)

in which R⁷ is C₁₋₄₀ alkyl, H, —OR or —OH radicals.

R⁷ may be C₁₋₄₀ alkyl that is optionally halogen-substituted, linear,cyclic, branched, aromatic, saturated or unsaturated. R⁷ may be an alkylgroup having C₁₋₆ carbon atoms, or a phenyl radical. The halogensubstituents may be selected from fluorine and chlorine. R⁷ may beselected from methyl, ethyl, phenyl and H. The composition may comprisefrom 0.1% to 10%, or from 1% to 5%, or from 2% to 4% of the MQ resin.

MQ resins are available from Wacker-Chemie AG, D-81737 München, Germany.For example, MQ-RESIN POWDER 803 TF is a co-hydrolysis product oftetraalkoxy silane (Q unit) and trimethyl-ethoxy silane (M unit) and canbe seen as a three dimensional network of polysilicic acid units whichare endblocked with trimethylsilyl groups. Some residual ethoxy andhydroxy functions are present. MQ resins are also available from DowCorning. For example, Dow Corning® MQ-1640 Flake Resin is a combinationof MQ and T propyl silicone resin and has the INCI name: Trimethylsiloxysilicate (and) Polypropyl silsesquioxane.

The composition may comprise an ether of a water-soluble polyhydricalcohol. The ether of a water-soluble polyhydric alcohol has theadvantage that it is able to prevent the aminosilicone and the siliconeresin from forming a complex. The ether of a water-soluble polyhydricalcohol may be a non-polymeric, amphiphilic compound. Indeed, theaminosilicone comprises amino side chains, which lend hydrophiliccharacter to the aminosilicone, and the silicone resin typically ishydrophobic in nature. Thus where the ether of a water-solublepolyhydric alcohol has amphiphilic chemistry it can interact with boththe aminosilicone and the silicone resin and keep them from clumping,and also from precipitating. The composition may comprise ether of awater-soluble polyhydric alcohol, wherein the ether of a water-solublepolyhydric alcohol is selected from the group consisting ofdiethyleneglycol monobutylether, ethylene glycol monohexyl ether, and amixture of diethyleneglycol monobutylether and ethylene glycol monohexylether. The composition may comprise from 0.01% to 20%, or from 0.1% to10%, or from 0.5% to 5%, or from 1.0% to 5%, or from 2% to 5% of anether of a water-soluble polyhydric alcohol.

A suitable product for use in the present invention is available underthe trade mark Wacker®/BELSIL ADM 8301 E by the company Wacker-ChemieAG, D-81737 München, Germany. This product contains from 10% to 20% ofpoly[3-((2-aminoethyl)amino)propyl]methyl(dimethyl)siloxane,hydroxyterminated, which is an aminosilicone. It also contains from 0.1%to 0.2% octamethylcyclotetrasiloxane and from 1% to 5% of an MQ siliconeresin. The product also contains from 1% to 3% ethylene glycol monohexylether and from 5% to 10% diethyleneglycol monobutylether. Said productis described in US2006/0041026A1 which is incorporated herein byreference. A similar product is Wacker® HC303 also commerciallyavailable from Wacker-Chemie AG.

The thickening system may comprise a deposition enhancer. The depositionenhancer may be a hydrophilic and non-ionic polymer, and wherein thedeposition enhancer may have a weight average molecular weight of from700,000 Dalton to 3,000,000 Dalton. The deposition enhancer may beuseful for aiding the deposition of the aminosilicone and silicone resinas well as any pigment and/or coloured material on to the hair fibre. Inparticular, the deposition enhancer may have the advantage that moreaminosilicone and silicone resin as well as any pigment and/or colouredmaterial stays on the hair fibre rather than dripping or sliding off thehair fibre. Indeed, in view of the physical structure of a head of hairi.e. a plurality of fibres that are in close proximity to one another,capillary action plays a role with regards to fluids on hair. Hence, thedeposition enhancer may be useful for preventing the capillary actionfrom stripping the aminosilicone, silicone resin and pigment and/orcoloured material from the hair.

The composition may comprise from 0.01% to 5% of the depositionenhancer. The composition may comprise from 0.05% to 4%, or from 0.075%to 3.5%, or from 0.1% to 3%, or from 0.1% to 2%, or from 0.15% to 1% ofthe deposition enhancer.

The depositionenhancer may conform to the formula H(OCH₂CH₂)_(n)OH wherein n has anaverage value of from 40,000 to 50,000. The composition may comprisefrom 0.01% to 5% deposition enhancer. The composition may comprise from0.05% to 4%, or from 0.075% to 3.5%, or from 0.1% to 3%, or from 0.1% to2%, or from 0.15% to 1% of the deposition enhancer, wherein thedeposition enhancer may conform to the formula H(OCH₂CH₂)_(n)OH whereinn has an average value of from 40,000 to 50,000.

Solvent

The composition comprises water. The water acts as a solvent. Water isuseful because it provides a hydrophilic phase, which the hydrophilicportions of the components can interact with. Water is also usefulbecause it provides a fluid phase meaning that the composition can be inliquid form and therefore easily mixed with other fluids. Thecomposition may comprise from 40% to 90%, or 50% to 85%, or from 55% to80% of water. The solvent may comprise water and wherein the compositioncomprises from 50% to 85% of water.

The composition may comprise glycerol, ethylene glycol,propylene glycol, or a mixture thereof.

Anti-Freeze Agent

The composition may comprise an anti-freeze agent. An anti-freeze agenthas the advantage that it lowers the freezing point of a composition andconsequently can prevent the composition from freezing, which canprevent any unwanted side effects of freezing and/or subsequent thawing.The anti-freeze agent may be a volatile alcohol, for example a volatilealcohol having from 1 to 8 carbon atoms and being miscible in water. Thecomposition may comprise from 0.5% to 30% volatile alcohol, wherein thevolatile alcohol may have from 1 to 8 carbon atoms and is miscible inwater. Miscibility in water is useful in view of the advantages of usingwater as a solvent. Indeed, the solvent may be water and/or the majorityof the solvent is water. Since the present first aspect is “forproviding a film on keratin fibres”, the volatility of the alcohol canbe chosen such that solvent and other non-film-forming compoundsevaporate.

Film Formed

The composition is for providing a film on keratin fibres. According tothe present invention, the film has certain properties that enable it toprovide a durable film that is neither sticky nor flaky. The physicalproperties of films can be defined parametrically in various ways—forexample in ROHM AND HAAS European patent EP1419759B1 granted on 26^(th)Dec. 2012, the composition claimed was defined by the film produced bythe polymers and said film having a certain tensile storage modulus at20° C. and storage modulus at 70° C. According to the present invention,the film has certain properties defined by the change in fluidity factorof the film when it is dried. Indeed, when drying the composition spreadwith an average wet thickness of 37 micron the fluidity factor ismeasured to form a drying curve of fluidity factor over time, whereinthe fluidity factor is within the range of 10 Hz to 0.001 Hz within thefirst 15 minutes of drying and the fluidity factor reduces by at least afactor of 100 within the first 15 minutes of drying. The drying curve offluidity factor over time is measured according to the fluidity factormeasurement method and at 23° C. and ambient conditions.

The fluidity factor is measured by creating a drying curve of fluidityfactor (y) over time (x). The fluidity factor is measured by opticaltechnology based on diffusing-wave spectroscopy. This methodology isdiscussed in Brun et al. Film formation of coatings studied bydiffusing-wave spectroscopy, Progress in Organic Coatings 61 (2008)181-191, in Snabre et al, US2008/0043233A1 published on 21^(st) Feb.2008, and in Dihang et al, “Film formation analysis by optical methods”,Technical Update, Surface Coatings International, Issue 2008/X, p. 1-4,which are incorporated herein by reference. In Brun et al. the techniqueis set out and this paper explains that the temporal fluctuations of thescattered light are directly related to the motion of scatterers(particulate matters) inside the sample, which motion is directlyrelated to the viscoelastic properties of the medium. When a film isformed, the motion of scatterers slows down as the film progressivelyforms due to an increase of the film coherence and viscosity: as aconsequence, the speed of the intensity fluctuations on the speckleimage decreases with time. Sections 2 and 3 of Brun et al. explains howthe measurements are taken and these sections are incorporated herein byreference. In short, a liquid composition is painted onto a substrate ata specific thickness and then immediately analysed via laser light—themolecular order is measured over time as the composition dries to form asolid film. The speckle rate discussed therein is the same as thefluidity factor reported herein. FIG. 7 of Brun et al. depicts theclassical phases of the drying process observed—in the different phasesdifferent levels of molecular order are achieved. Sharp changes in thespeckle rate occur at several points in time indicating the time pointswhen one phase ends and the next begins. In the first phase (phase I),solvent evaporates and the fluidity factor decreases. This first phasecorresponds to a concentration stage, the water evaporates from the filmsurface, water molecules migrate from the liquid to the atmospheregenerating currents and hence fast Brownian motion. The end of phase Iis indicated by T₁. The second phase is relatively disordered as themolecules pack together to reach a reasonably ordered state. Theturbulent signal and the high concentration in solid indicate thatscatterers start to interfere in the motion of each other; the particlesstart to rearrange and organise. The end of phase II is indicated by T₂.Following T₂, the curve remains relatively smooth. In the third phase(phase III), the ordered molecules retain their order but are pushedcloser and closer together as the composition dries. The drasticreduction of the scatterers mobility can be attributed to thedisappearance of the bulk water, close-packing of particles beingreached. FIG. 7 of Brun et al. depicts a reduction of speckle rate (Hz)from 10 Hz to 0.001 Hz in the first 40 minutes, hence a reduction influidity factor of 10,000 in the first 40 minutes.

In the fluidity factor measurement method, the fluidity factor i.e.Multispeckle Diffusing Wave Spectroscopy (MS-DWS) measurements arecarried out using the Horus® film formation analyser from Formulaction(10 impasse borde basse, 31240 L'Union France www.formulaction.com)according to the manufacturer's instructions. The instrument is in abackscattering configuration: the camera sensor (CMOS) and the lasersource are on the same side with respect to the analysed sample and arecombined in a single measuring head. The laser source is a standardlaser diode of 0.9 mW with a wavelength of 655 nm. The camera is astandard 320×240 pixel sensor with a maximum frame rate of 30images/sec. The area analysed is a rectangle 1 cm long and 0.5 cm wide.The substrate used (upon which the composition is applied) is a1,1,1-trimethyl-1-pentene (TMP, 2,3-dimethyl-2-hexene) coatedpolyurethane skin mimic.

A suitable skin mimic is disclosed in WO2008/084442A1, which isincorporated herein by reference. To form the first layer of the skinmimic, spray coat a mold (laser-etched metal mold being 89 mm by 178 mm)with a liquid polyurethane composition (for example a 1:1 mixture ofSkinFlex SC-893 stretch paint [aliphatic polyurethane gloss paint] andSkin-Flex SC-89 thinner from BJB Enterprises, Inc.), to create a layerhaving a thickness of 300 micron, and allow to dry for at least 12hours. Prior to pouring, degas the liquid polymers sufficiently toremove undesirable trapped air bubbles. Allow to cure/dry for 24 hours.To form the top layer, pour 1,1,1-trimethyl-1-pentene (TMP,2,3-dimethyl-2-hexene) to create the top layer having a thickness of0.85 cm. Allow to cure/dry for 24 hours prior to use.

The composition according to the present invention is applied to thesubstrate via a flat sponge applicator providing an average wetthickness of 37 micron i.e. the composition is spread such that anaverage wet thickness of 37 micron is provided. “Average wet thickness”means the thickness of the composition applied to the substrateimmediately prior to starting the measurements i.e. immediately prior toallowing the composition to dry to a film. The wet thickness can bemeasured via microscopy and then the average wet thickness iscalculated. Average wet thickness is measured by measuring the thicknessof the film at 8 positions as per the below scheme, which is the 1cm×0.5 cm area measured by the Horus® film formation analyser, dividedinto 0.25×0.25 cm squares, i.e. eight measurements are made of thethickness of the wet film where each measurement must be measured in oneof the below squares.

To calculate the average, the sum of the eight measurements iscalculated and then divided by eight. This average wet thickness must be37 micron. Where the average wet thickness is from 36.5 micron to 37.4micron, then these thicknesses are considered to fall within the scopeof 37 micron. The average wet thickness does not include the thicknessof the substrate.

The fluidity factor of the film is measured as it dries to form a dryingcurve of fluidity factor over time. The measurements are analysed withthe HoruSoft software and presented as a graph.

FIG. 2 depicts the fluidity factor over time of two compositionsaccording to the present invention. Composition A contains 15% BELSILADM 8301 E, 1% Salcare® SC 96, 0.2% PEG-45M, 1% 2-phenoxyethanol, 1%ethanol, 5% pigment and QSP deionised water. Composition B contains 15%BELSIL ADM 8301 E, 0.6% Salcare® SC 96, 0.2% PEG-45M, 1%2-phenoxyethanol, 1% ethanol, 5% pigment and QSP deionised water. Thefluidity factor over time is measured three times for composition A (A1,A2, A3) and twice for composition B. The fluidity factor for allcompositions for all curves starts between 1 Hz and 10 Hz (i.e. at 0minutes) and then reduces over time. After 15 minutes, all curves forall compositions are between 1×10⁻² and 1×10³ Hz i.e. between 0.01 Hzand 0.001 Hz. Consequently, the fluidity factor has reduced by at leasta factor of 100 within the first 15 minutes of drying.

The fluidity factor is within the range of 5 Hz to 0.001 Hz within thefirst 15 minutes of drying and the fluidity factor reduces by a factorof at least 100 within the first 15 minutes of drying. The fluidityfactor is within the range of 5 Hz to 0.002 Hz within the first 15minutes of drying and the fluidity factor reduces by a factor of atleast 100 within the first 15 minutes of drying. The fluidity factor iswithin the range of 5 Hz to 0.002 Hz within the first 10 minutes ofdrying and the fluidity factor reduces by a factor of at least 100within the first 10 minutes of drying.

The T₂ transition of the fluidity factor over time curve is achievedwithin the first 10 minutes of drying.

How to calculate the tandelta is shown below:

-   -   G′=Storage Modulus    -   G″=Loss Modulus    -   tan δ=Loss Factor

$\begin{matrix}{\frac{G^{''}}{G^{\prime}} = {\tan \; \delta}} \\{{{G^{*}}(w)} = {{{G^{\prime}(w)} + {\; {G^{''}(w)}}} = \sqrt{G^{\prime \; 2} + G^{''\; 2}}}}\end{matrix}$

The hair strands treated with the composition H were compared to thehair strands treated with the comparative composition I under a D65light box. The assessment was rated as follows:

−3 −2 −1 0 1 2 3 Obvious Noticeable Slightly Equal Slightly NoticeableObvious worst worst worst better better betterThe reference was a non-treated hair strand.Hair strands treated with the composition H exhibited a noticeablebetter effect on hair than the reference.Hair strands treated with the comparative composition I exhibited aslight worst effect on hair than the reference.When the composition comprises a MQ resin, the color effect on hair isbetter noticeable than when the composition does not comprise a MQresin.

Effect of Hair Wash

The hairs strand treated with the respective composition H or I werewashed for 30 seconds with water then 30 seconds with 0.5 mL of WellaProfessionals Brilliance Shampoo, and then 30 seconds with water.Each treated hair strand was blow dried manually with a conventionalblow dryer for 2 minutes. After each 30 seconds, the treated hairstrands were combed from the top to the bottom of the hair strands.The hair strands treated with the composition H showed a good pigmentadhesion to the hair, by visual assessment.However, the hair strands treated with the comparative composition Ionly showed a slight pigment adhesion to the hair, by visual assessment.

Hair Feel

The hair strands treated with the respective composition H or I werepulled through thumb and index fingers. The treated hair strands wereassessed versus an untreated hair strand.The hair strands treated with the composition H showed a noticeablecoated effect. However, the hair strands treated with the comparativecomposition I only showed a slight coated effect.

Water Dipping Test

The hair strands treated with the respective composition H or I weredipped for 15 times for 15 seconds in 200 mL of distillate water. Apicture was taken after the pigments have sedimented.It has been observed that the hair strands treated with the compositionH lost few pigments. However, the hair strands treated with thecomparative composition I lost much more pigments versus the hairstrands treated with the composition H.

CONCLUSION

When the hair strands are treated with the composition H which comprisesa MQ resin, versus the comparative composition I, the treated hairstrands exhibited an improved colored performance, with an increasedpigment adhesion on hair, and a better resistance to wash fastness.
